sum 1 or 2 I PAIENTED AUG 7 I975 SHEU 2 [IF 2 COMBINED SNOW SHOVEL, WHEEL BARROW AND DOLLY BACKGROUND OF THE INVENTION The invention relates to multi purpose, manually operated carrying devices, more particularly to a device which in accordance with the need can be utilized as wheel barrow, dolly or snow shovel.
The object of the invention is to provide a device of the above defined art which is practical to use and simple to convert in order to be operated as a wheel barrow, dolly or as a snow shovel, respectively. The device will be particularly suitable for houseowners gardeners and the like, i.e. people meeting the need for a show shovel during the wintertime, a garden wheel barrow during the spring and summer season, and furthermore need a dolly suitable for carrying more heavy objects.
A particular property of the device in accordance with the invention is that, as a two-wheeled wagon it can be assembled in two fashions such that the device is suitable as a wheel barrow or as a dolly for carrying more heavy objects. By means of simple handgrips the device can be transformed from one form or function to another.
The device in accordance with the invention is of the kind comprising a wholly or entirely flat bottomed, shallow trough-shaped container provided with a sidewall on each opposite side and one end wall or transverse wall at its rear end, and the device is adapted to receive a pair of wheels and furthermore a rodshaped,
preferably U-shaped handle member. The device in accordance with the invention is particularly characterized therein that the handle and the container are so adapted to each other that the handle may be fixed to the container in two positions, namely first in a position along the substantially flat bottom part of the container, when the device shall be utilized as a dolly for carrying bags or the like, and second, in a position fixed to the end wall when the device shall serve as a wheel barrow or a snow shovel. The wheels can be removed to allow the device to serve as a snow shovel.
In a preferred embodiment of the invention the handle member is pivotally supported on the container about an axis which extends across the container at the corner or transition zone between the rear end wall and the flat bottom of the container. The device is transformed from serving as dolly to a wheel barrow simply by pivoting the handle member about the container to positions against the substantially flat bottom of the container or against the end wall, respectively. The handle member and the container are fixedly attached to each other in their respective positions by means of clamps or the like'which are positioned between the handle member and the container.
A further feature of the invention is that the support shaft for the wheels also is utilized as the pivot for the handle member.
BRIEF DESCRIPTION OF THE DRAWINGS An embodiment for a device in accordance with the invention is illustrated in the accompanying drawings, wherein:
FIGS. 1 and 2 show, respectively, a perspective view and a view from the bottom of the device while the same is assembled with a handle member but without wheels, such that the device is ready to be utilized as a snow shovel.
FIG. 3 is a perspective view of the device adapted as a wheel barrow.
FIG. 4 is a further perspective view of the device when it is adapted as a dolly for carrying heavy bags or the like.
DETAILED DESCRIPTION OF THE INVENTION As it appears from FIG. I or 2, the open container or shovel 1 has a substantially flat bottom 2, the fore part 3 of which slopes at an acute angle upwardly from the plane of the rearly positioned flat bottom part 2. The container is provided with a substantially upright endor transverse wall 4 and furthermore provided with side walls 6 and 8 which towards the fore end converge to zero, such that the fore edge of the container provides a plate-shaped edge. The bottom portion and the end wall are pro-vided with two mutually spaced, parallel wide grooves or recesses, portions 12 of which are in bottom part 2, portions 14 of which are in fore part 3, and portions 15 of which are in end wall 4, and which are adapted to support and receive a two part handle member 20.
Transversely of the container substantially at the transition zone or corner between the bottom 2 and the end wall 4 is provided asupport shaft 13 having extensions on each side of the container whereon are removably mounted wheels 16 and 18. The shaft 13 is positioned through portions 12 of the recesses formed in the container. The shaft provides-pivotable support at points 21 for the side legs 22,24 on the handle member. The handle member is for instance made of steel piping and has a transverse leg 26 serving as-handle. On each side of the legs 22 and 24 are providedslideable clamps 28, each of which has an ear or hook 30 engageable with the adjacent edge of the container as illustrated in FIGS. 1 and 3, and operative to fix the handle member to the container in two alternative positions.
As it appears from the Figures the side legs 22 and 24 are provided with a bend in transition zone 31 such that the side legs have angles which correspond to the angle between the two parts 2 and 3 of the container bottom. Furthermore, in the position of FIGS. 1-3, the handle member legs 22 and 24 come into firm rest against the container in the recess portions 15, and in the position of FIG. 4, legs 22 and 24 rest in recess portions 12 and 14 in bottom part 2 and fore part 3, respectively.
A correct angular adaption between the handle member and the container, respectively, has proved quite important in order that the centre of gravity of the entire device is located correctly for easy driving.
The wheels 16 and 18 are threaded onto the extensions on the shaft 13 and are, for instance by means of pins 17 or the like, fastened thereon.
FIGS. 1 and 2 show the device with the two wheels removed and thus ready to be used as a snow shovel, the container serving as a scoop. FIG. 3 shows the device with wheels and adapted to be utilized as a wheel barrow such that it will be suitable for carrying grass, leaves etc. FIG. 4 shows the device adapted as a dolly. The handle member is here, as compared with the situation shown in FIG. 3, pivoted around the container and fixed against the container bottom such that the end wall 4 constitutes the actual bottom of the vehicle, now serving as a dolly. It appears that the centre of gravity of the goods carried therein will be positioned substantially straight above the wheel shaft, thus making the dolly suitable for carrying more heavy loads, such as bags, boxes or the like.
